One of the most important factors affecting the air quality is aerosols transferring microorganisms and deposits to the respiratory tract. The purpose of this study was to measure the concentration of suspended particles in outdoor and indoor ‎of Dena hospital and determine the relationship between these parameters.‎ Methods: A cross-sectional study was done in Dena hospital in Shiraz in 2012 by collecting 315 samples for analysis. Sampling was performed by an Aerosol Mass Monitor sampler, (Model GT-331, Japan) to ‎measure the particle concentration of PM10 and PM2.5. The concentration of indoor suspended particles ‎in air in different wards of the hospital were measured and compared with hospital outdoor particles. The data ‎were analyzed using SPSS version 16. Results: The findings showed that average PM10 in the air in hospital wards as well as all outdoor air samples were significantly lower than the 24-hour WHO and the 24-hour USEPA standards (p<0.001). Significant relationships were observed between the average concentrations of PM2.5 in all the sampling sites ‎and the 24-hour WHO and the USEPA standards (p<0.001‎)‎. Conclusion: The concentration of suspended particulate in indoor air was lower than outdoor air that represents the appropriate function of the sectors ventilation systems.
